Cellulose, 6-carboxy, also known as cellulose 6-carboxylate or cellulose carboxylate, is a chemical derivative of cellulose, a naturally occurring polysaccharide found in plant cell walls. This modified cellulose contains carboxyl groups (-COOH) attached to the sixth carbon atom of the glucose units in the cellulose chain. The introduction of these carboxyl groups enhances the hydrophilic properties of cellulose, making it more soluble in water and increasing its reactivity. This chemical modification has various applications, such as in the production of hydrogels, drug delivery systems, and as a component in certain types of纸张 and textiles. The increased reactivity and solubility of cellulose, 6-carboxy, also make it a valuable material for research in materials science and biotechnology.
The CAS Registry Mumber 9036-73-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,3 and 6 respectively; the second part has 2 digits, 7 and 3 respectively. Calculate Digit Verification of CAS Registry Number 9036-73: (6*9)+(5*0)+(4*3)+(3*6)+(2*7)+(1*3)=101 101 % 10 = 1 So 9036-73-1 is a valid CAS Registry Number.
